In Figs. l to 3 of the drawings7 the numeral ZDIi'ndcatestwo side" frames; suitably` connected together 'as' at 2|' at; various locations. There is supported by.` thisframe workla table or plat-- form 22 and running in the same is an endless belt conveyor ZS/that runs between two guides' 24;

the strip ofdough being confined by these guides and being .moved by this belt conveyor.

Th'e baker applies the dough lat the receiving or left hand end of the platform 22l inalignment.

with kthe belt conveyor 23having previously applied sufcient flour, or thel like, to theplatforrn ahead of the belt, so that the sheetfof dough is suitablyy ,dusted on.v its lower face. The baker pushesthis hand formed. sheet of. dough. into the throat formed by the guidesz projecting .to-

wardthe lettv beyondthe yendless belt conveyor 2?.and thesurplusdough onaeithersideof these. guides.y is .removed-and. subsequently worked -u-py into.another..sheet. f TheA baker. i-nf-ieeding this dough tries to form a fairly flat sheet of approximately proper thickness and width.

Before this dough is exhausted, the baker prepares another piece so that at the proper time he can crimp the latter to the former before it passes completely through the sheeter.

The endless belt conveyor 23 then carries the dough forward and to the right in Figs. 1 and 2, whereupon, while on the conveyor, the sheet of dough encounters a flattening element 25. AThis flattening element 25 has about 11/2 throw to and fro towards and away from the conveyor 23 and at each reciprocation it mashes or lattens out the dough between the two guides and on the conveyor.

Mounted in each of the upright portions 23a of the frame structure 20 is a guideway 26 which mounts a crosshead 21 providing a bearing for one end of the shaft 28. This crosshead has a rearwardly directed arm 29 which pivotally supports as at 30 the beater 25, the latter having forwardly extending arms 25a.

Each crosshead 21 is provided with a screwthreaded attachment member 3| and these two members mount at their upper ends bevel gears 32 that mesh with similar bevel gears 33 carried by the shaft 34. This shaft 34 mounts a handwheel 35 on one end or the shaft may be extended and may be provided with a handwheel at both ends. By means of this adjustment the height of the beater 25 and the height of the pressure roller 36, which is the upper roller engaging the upper surface of the sheet of dough, may be adjusted.

Immediately beneath roller 36 is another roller 31 which has a fixed position and said roller'31 has its upper, longitudinal element substantially coplanar with that of the platform or table 22 and the upper run of the belt conveyor 23.

Immediately below the roller 31 is another roller 38 and forwardly thereof is a roller 39 mounted on shaft 40 carried by crossheads 4I slidably supported in the ways or guides 42. A screw element 43 is arranged to advance and return the roller 39. Each of these screws `is provided with a bevel gear 44 and these bevel gears mesh with similar gears 45 carried by a shaft 46. A handwheel 41 is arranged to simultaneously move the crossheads 4I forwardly or rearwardly and thus move the roller 39 forwardly or rearwardly away from or toward the roller 38. rI'he dough advanced by the conveyor 23 passes be.- neath the beater 25 and thence between the rollers 36 and 31 and then drops vertically between the two rollers 38 and 39. 1

There may be supported above the roller 36 a suitable dusting arrangement, not shown, the detailed construction of whichmay be similar to that hereinafter described. Suffice, it is indicated by the numeral 48 in Fig.`2 and supplies flour to the` top surface or face of the dough sheet so that the sheet will not adhere to the upper roller 36, it being remembered that the baker has sufficiently dusted or iioured the lower face of the sheet ahead of the conveyor 23.V This dusting of both sides of the sheet of dough also prevents adherence of the sheet to the subsequent rollers 33 and 39. One function ofthe beater before mentioned is to prevent the `dough from stratifying and tearing as it is borne through the two upper rollers 36 and 31.

As the sheet of dough prepared by the baker is exhausted, the baker prepares another sheet and places it immediately adjacent the rear end of the advancing sheet, which he has previously prepared, and then crimps the ends together to unite the sheets to insure continuous sheet formation for continuous production by subsequent apparatus.

In Fig. 2 the numeral 49 indicates a main power drive. A chain drive 50 passes over a sprocket pulley 5l and then passes under a sprocket pulley 52, the latter being carried by the shaft 38a, of a roller 38. It also passes over a sprocket pulley 53 carried by the shaft 49 of the roller 39. This driving chain passes over a tensioning sprocket pulley 54, mounted on a pivoted arm 55 and spring constrained as at 56. This, as stated, is a tensioning arrangement. In this way it will be observed that the rollers 38 and 39 are positively driven and in opposite directions by said chain belt 50,

Coaxial with the center of the sprocket pulley 5I is an arm 51 and mounted on the end thereof is a gear 58. This gear 58 meshes with a gear 59 also coaxial with the sprocket pulley 5I and rotatable therewith. Thus the pinion 58 rotates at a relatively high speed. The pinion' 58 has an eccentric pin 60 and a rod 6I is pivotally mounted thereon so that, in the rotation' of the gear 58, the rod 6l is reciprocated generally inthe up and down direction.

The upper end of this eccentric rod 6i is connected to a lever arm 62 which is rigid with the shaft 36 which supports the beater 25 by means of the extensions or arms 25a. It will be remembered the shaft I30 is mounted in arms 29 constituting extensions of the crosshead 21. When the crossheads are elevated, arms 29 are elevated therewith and in a like amount, and accordingly, by means of the rod construction 6|, the arm 51 rotates clockwise to permit such elevating movement withoutv interference, yet at the same time retaining the pinion 58 in mesh with the gear 59 for power application to the beater.

The superposed upper rollers 36 and 31 are suitably driven from the main power source. The l shaft 31a of the lower roller mounts a sprocket pulley 63 which is driven by a chain drive 64, in turn driving a sprocket pulley 65 carried by the shaft 66 of the pulley or drum 61, which supports the forward end of the conveyor 23. The rearward end of this conveyor is supported by the drum 68. The ratio of the drives is such that the peripheral speed of the superposed drums or rollers 36 and 31 is approximately twice that of the peripheral speed of the conveyor 23. This power application, if desired, may be provided with a tensioning device such as illustrated in Fig. 2 and indicated by the numerals 54 to 56, inclusive. For clearness, this tensioning device is intentionally omitted from the present disclosure. It might be here stated the power connection from shaft 49 to the shaft 31, etc., is positioned upon the opposite side of the machine from the side illustrated in Fig. 2. The rollers 36 and 31 have substantially the same peripheral speed as the rollers 38 and-39,

Positioned beneath the aforesaid mechanism, is an endless conveyor arrangement 10, the rearward end thereof passing over drum 1I and the forward end thereof passing over drum 12, see

Fig. 2. The lower run of this conveyor is directed upwardly as indicated at 10a, and 19h, by means of the idlers 13. Suitable tensioning means may be provided, such as hereinbefore described, and more specically illustrated and indicated by numerals 54to 56, inclusive. For clearness, same is omitted herefrom.

The power fori driving' the oonveyor'xl israp-l plied to the drum 12 and such power application is encased in the housing portion 'ML The'peripherarspeed of this conveyor 'l0 is substantially the same'as theperipheral speed of the cooperating.

The tanki'is connected by a line S3 to a header Mbwhich in turn discharges to each of the' tanksV 'land- 19a and' maintains pressure on said tanks;- Con'sequently, air pressure forces the liquid in tlfe'se/tanks`V through the conduit 85 tov the oil spray headsfll and by means of conduit 86 to the@ water spray head` l8`E from the tanks 19 and :"f" "l9a',-1respe`ctively.` The purpose of the oil sprayy is to grease-all except one narrow edge stripv ofthe entire top surface of the sheet of dough which hafsf-b'een previously dusted for non-adherence to theroller, sol that 4the various materialssupplied to'fthe top surface 4of the dough will adhere there-- to; 1 suchl materials, as stated previously; being sugar; cinnamon,chopped nuts,y raisins, et cetera.

All-connectionsA to the several tanks- 19 and 19a with the -air tank 82 are provided with valves and thelsveveraldischarges from these tanks to the nozzles -are provided with valves, the same being omitted for clearnessin Athe instant illustration:v

but such valves are of regulating and cut-ofi-` character.

Fifmfthe foregoing,- therefore, it will be noted i that: as the sheetV of dough is advanced-it is sprayed with Water on its lower edge, referring 1 only-to"Fig.-1, for example a one inch width, and

is sprayed with oil across the remainder of the' r The purpose of sprayinggthis entire upper face. edge with water is to insure that when the' dough is-roll'ed-up, the resulting moistenededge of the dough' sheet, then in roll formation, will adhere to'- the-adjacent portion ofthe roll and be scaled thereto, and by a mechanism to be hereinafter described.

I |62 The shaft structure: 121e' The shaft |--see Fig; 13is extended. up` wardly and into a housing arrangement |22-|24. The shaft |05a. therein mounts bevel pinion |23. The bevel pinion |23 meshes with the bevel pinion |25 on a shaft |26 that supports a roller structure |21, the same being very elongated, relatively speaking, and normally biased relative to the direction of travel relative to the belt 10, as shown in Fig. 1. This roller |21 rotates clockwise, looking at the lower or forward end of the roller, so that as the advancing dough sheet on its upper edge, see Fig. 1, first engages the roll |21, the dough is carried upwardly and then gradually turns back upon itself and starts the initial roll of the sheet so as to form a longitudinal roll of dough.

Shafts |05 and |05a have a detachable spline connection |05b. Housing |24 carries shaft-|2$ and, by handle I24a, can be elevated when clamp |2419 is loosened so that roll |21 can be swung about the axis of shafts I [l5-|0511. The biased roll |21 thus can be locked in any biased position or lie parallel to belt as desired.

Immediately above roller |21 there is supported another roller |28 parallel to the roller |21and counterweighted as at |29. This roller is carried by shaft |30 which rides in a somewhat vertical slot |30a in housing |24. The gear |3| meshes with the gear |2511 carried by the shaft |3|a. Gears |3|b and |2512 on shafts |3|a and |0527, respectively, mesh with each other. The gear |2511 is slidable on countershaft |3|a and spring |3|c normally constrains gear |25a into mesh with gear |3|. The gear train relationship is such the rolls |21 and |28 rotate in the same direction and roll |28 can elevate as the: dough roll increases in size, yet be positively driven, which insures pressure contact between portions of the dough roll as it is being rolled up from the sheet. The counterweight |29a for the roller |28 may be suitably adjusted on the support |29 and hence,

this roller |28 controls the tightness of the dough,

been moistened by the water supply nozzle 13` so that when that portion of the dough sheet enfgages the rolled up portion of the dough sheet, the pressure roller |28 causes the moistened portion of dough sheet to seal to the main body portion of the dough roll. The completed dough roll then advances forwardly and angularly, that is, to the right in Fig. 1, and downwardly relative to the two rollers |21 and |28, see Fig. 1, until Vit reaches the ends of these rollers. In other words, the roll changes travel direction from the direction of travel of the sheet of dough.

Adjacent the ends of the rollersy |21 and |28, there is provided a pair of spaced endless conveyors in the form of guides. Herein the numeral |32 indicates one of said inlet conveyors, the same being at right angles to the supporting plane of the conveyor 10 and terminating above the same and carried by the frame work |34 of the turnup and pressure rollers and by means of the arm |35 mounting rollers |36 at opposite ends. If desired, the connection between |34 and |35 may be of pivotal character as at |35a and arranged for angular adjustment. Therefore, the cantilever type supporting frame Work |34 carriedby the housing |22 may be swung into any desired inclined relationship and the conveyor |32 may be arranged so that its lower run, having reference 8 to Fig. 1, will Valways travel parallel to the edge of the belt 10.

Adjacent the belt |32 is another belt |31 which is carried by pulleys |38, the latter being supported by a support structure |33 that may be moved forwardly or rearwardly relative to the frame 20 and the discharge end of the belt 10 by means of the hand crank |40.

The purpose of this construction is to insure that the receiving end of this belt |31 is in proper positionto receive the roll as it is discharged from the forward end of the turn-up roller. Also, this structure |39 may be so arranged that the conveyor |31 may be moved closer to the conveyor |32 or therefrom, as desired. This conveyor |31 is driven by a shaft |4| having gear |42a driven by a gear |42 on shaft |43 by means of a bevel gear |44 meshing with a bevel gear |45,`on shaft lll, that is, the shaft which mounts the drum 12.

Whenever it is desired to positively drive the belt |32,k the power drive may be derived from the primary shaft |5d in the housing |24 and carried along through the frame structure |34. However, this usually is not necessary just as long as one of the two confronting guide and roll sealing belts |32-|31 is positively driven. The dual belt drive under certain circumstances may be highly desirable and when it is desirable, the last mentioned drive to belt |32 may be incorporated, in addition to the first mentioned drive, to belt |31, the latter being derived from the left end of the shaft referring to Fig. 1.

The foregoing invention, excluding a specic description ofy one or more types of material dispensing apparatus associated with one or more of the sockets 81 previously described, and included in the plate formation 20h, see Fig. 1, constitutes the primary form of the invention. The dough roll formed by this device is discharged from the belt 10 from between the sealing and guiding conveyors |32 and |31 to any suitable container, endless belt structure, platform, or the like.

However, in the present invention, there is provided a power driven cutoi for forming uniform sections of the roll. This mechanism is hingedly mounted on the frame 20 as at |46, that is, the discharge end of the machine. This includes a frame arrangement |41 which is provided with a tubular element |48 that receives the dough roll as it leaves the belt 10 on the drum 12.

Beneath tubular element |48 and pivotally mounted in the frame work |41 is an open work wheel arrangement |49, the bars |50 of which constitute cutting elements since they strike across the bottom of the tube |48 and hence cut through the dough roll to sever that part of the dough roll which has passed through the tube |48. This cutting wheel |40 is intermittently rotated and preferably is intermittently rotated by means of a ratchet 5| and a pawl |52.

The pawl |52 is suitably actuated by means |53 which is of reciprocatory type and which is connected to the core |54 of a solenoid |55, current thereto being supplied by lines |56. All of this mechanism is carried by the auxiliary frame |41 pivoted at I 46. Whenever desired, all of this mechanism can be swung away from in front of the discharge end of the belt 10 for the purpose described.

Referring to Fig. 2, it will be noted that shaft |43 is extended and enters the housing |51, and that the current wires |55 also enter said housing. The shaft |43 includes a bevel gear |58 which meshes with-the gearill'dcarried -by the shaft |60.

This shaft 16.0 mounts a contact plated 6| -of insulation material. MountedA .therein are" suitable contacts |62. YA slidable brush |63 rides the disc or plate-18|. 'A-lineldfrom said brush leads to the solenoid. A contactdz'zengages plateu|181ion and plug |56a, -Withsthe .result-.that the periodicity of operationbf sole'rid"|'55 and hence the cutofjff-wheel |49 for anyconstant rotation -of the the selectivity of the slidable brush connection IBS-|62. Since switches of this particular type are comparatively well known in the electrical art, no further description or illustration of the same is believed necessary herein.

Reference now will be had to Figs. 6 to 10, inclusive. In this connection it is to be observed that the machine may be provided with at least three hoppers. each of which would be substantialiy identical to the the others except for the diiference in the screen plates as represented by Figs. 8, 9 and 10, the screen plate shown in Fig. 8 being suitable for the distribution of raisins, et cetera; that shown in Fig. 9 being suitable for the distribution of chopped nuts and material of that size, and that shown in Fig 10 being suitable for the distribution of powdered material, such as powdered sugar, sugar, cinnamon, et cetera.

It will be recalled there were provided three sockets 81 in the plate 2Gb. Referring to Figs. 6

and '7, there is illustrated a body portion |68 having a collar |68a and a tongue |69 below the collar portion. The body portion |68 below the collar portion |886 seats in the socket 81 and the key or tongue |69 seats in the notch or slot 81hsee Fig. 1. The body portion |88 rotatably supports a shaft |18 which mounts on its upper end in chamber |11 a bevel gear |12, the latter meshing with the bevel gear |13 carried by shaft |14 that extends outwardly into the hopper formation indicated generally by the numeral |15. The detachable drive connection associated with the drive shaft 88 is indicated as at |18a in Fig. 6.

Hence, when the structure just described is associated with the socket 81 and the belt Il connects the pulley 9| with the split pulley 99 in registration therewith and the belt tension is adjusted as described, the shaft |14 of the hopper mechanism will be rotated at the predetermined desired speed. But one of these structures is illustrated in Fig. 1 and is designated broadly by the numeral |15.

The hopper structure |15 at each end rotatably supports the shaft |14, the hopper having a semicircular bottom portion |15a with a longitudinal throat |16 the full width of the hopper. Rotatably supported within the hopper and carried by said shaft |14 by means of the collars or discs |11 are the rods |18. These rods |18 constitute agitating elements. A screen |19 is interposed between the agitator and the hopper bottom |15a and is extended upwardly and anchored as at |88 to the side wall of the hopper. Portions |8| are reenforcing ribs which may have hand holes |8 la therein.

The length of this orice may be regulated by the slidably supported cutoff slides |82 having the inger pieces |83. When these slides are pulled back, see Fig. 7, the throat |16 can discharge whatever is passed through the screen |19. Clogging of the screen |19 is prevented by the "X10 .oagitat-,or arrangement.' fThe'screen includes `aperi `fturesril'z'liia'as shown'nFig. 8.

yf'Eigs; 19 and-".10: rmerely" showy a yslgllllly defent form of rscreen insofar .as i the i size Yand number cof-apertures isi-concerned. The illustration in y Figs,y Seto l0,..inclusiv.elare to be .considered as ..'-illustrativein character. L As 'previously set forth, "thels'peedof rotation lof' shaft "iii is determined ",bythe dual `adjustment-se`e"Figs.` 1 and 3. As 10` shown `in^Fig. ,1,"butone' material discharging i* hopper Vof cantilever supported type is illustrated.

The machine, however, is adapted to mount three of these material discharging hoppers-see Figs. 1-and"2.f*-Ihes`e immediately follow, insofar as dough sheet application is concerned, the oil and water spray applications.

Reference now will be had to Figs. 11 and 12. It is to be understood the same general type of drive connection and support is provided as is illustrated in Figs. 6 and '7. However, in this instance, the central shaft i'ill is not lutilized but an offset drive arrangement is utilized to drive one of a pair of meshing corrugated rollers. The hopper in this instance is indicated by the numeral |85 andthe two corrugated rollers, indicated by the numeral |86, have the ridges E81 that mesh with each other. The rotation thereof is as indicated by the arrows and the material carried around by the ridges and between the ridge and the hopper is discharged into the throat |88 and from it as at Hita is applied to the top layer oi the dough sheet therebeneath.

The hopper |85 is adapted to receive a creamy paste such as lemon, vanilla, or chocolate, et cetera, cream for example, or a jelly paste. In this form of the invention, the apertured screens naturally are not employed. Fig. 12 illustrates the bottom of the hopper shown in Fig. 1l and illustrates how the width of the paste discharged can be regulated to correspond to the width of the dough sheet therebeneath.

Pivoted at each end of hopper |85 at |88 is a cut-off arm |89 having frictional contact with the bracket i90 carried by the underside of the hopper. Portion 19| of the arm is the hand adjusting portion. Two dotted positions are illustrated. When positioned as shown (see right side dotted), minimum width of cream is discharged if both are positioned alike. A wider stream is discharged if both are positioned as shown (see dotted left hand side of Fig. 12). Full width discharge is effected when both control arms are positioned as shown by the full lines.

By the terminology water, as hereinafter used in the claims, the same is intended to comprehend within its scope water per se or an aqueous solution including milk, a syrup or the like, or other liquid suitable for the purpose described.

While the invention has been illustrated and described in great detail in the drawings and foregoing description, the same is to be considered as illustrative and not restrictive in character.

The several modifications described herein as well as others which will readily suggest themselves to persons skilled in this art, all are considered to be within the broad scope of the invention, reference being had to the appended claim.

The invention claimed is:

The method of continuousiy forming a dough roll for subsequent baking from a continuously advancing sheet of dough of uniform width and thickness without stratications or tears therein comprising, applying, continuously, prior to rolling, oil to the major Width of the sheet except for REFERENCES CITED the longitudinal edge portion to be last rolled, The following references are of record in the applying continuously Water to that edge portion, fue of this patent: progressively turning upwardly the oiled edge of UNITED STATES PATENTS the sheet and then progressively turning inwardly 5 the turned up edge upon the sheet while turning Number Y Name Date up the adjacent portion of the sheet until `the Re lnhlen --E--l --u- 'g1 watered edge is finally turned upon the resulting 9231360 Kruseans e a Jung l, 1909 roll, the second turning being aocompanied by'lo l 176648 CanOW-g-a-l Mar 21 1916 continuous application of uniform pressure to the roll as formed and regardless of roll diameter.
